Bristol Ridge does support ECC BTW, but one problem is that you can't use ECC with x16 chips (because ECC is 72-bit), so with 8GB of RAM and 8Gbit chips you have to choose between non-ECC/ECC single channel with x8 chips and non-ECC dual channel with x16 chips. 4Gbit don't have this problem but will become obsolete especially when 18nm ramps up, and while DRAM prices should decline when that happens...

What's the matter with x8/x16 chips and dual channel? I don't think it should matter.

Or do you mean that if you want exactly 8GB then it's hard to find a pair of 4GB DDR4 ECC modules? Well, just get 2x8GB if you are a performance nut.

Yes, what I am saying is that it is impossible with 8Gbit chips, but possible with 4Gbit.
